A speeding tanker truck carrying 6,500 gallons of treated sewage overturned in Gastonia around rush hour on Thursday, spilling nearly half its load into the roadway.

The crash happened around 5:10 p.m. on York Highway and Stagecoach Road. The tanker was headed north on York Highway (U.S. 321) and overturned while trying to turn left.

The force of the collision punched a hole in the tanker, and roughly 3,000 gallons of sewage spilled onto the roadway.

Members of the Gastonia Fire Department’s hazardous materials team patched the sewage leak in roughly 10 minutes. Photos from the scene showed firefighters with full-body haz-mat suits and oxygen tanks working in the saturated grass to fix the hole.

Crowder’s Mountain Fire & Rescue and Union Road Fire Department also responded to the crash. Because of their efforts, firefighters say none of the “sewage from the tanker truck contaminated the public water system,” according to a statement.

The truck’s driver was treated for nonlife-threatening injuries at Caromont Regional Medical Center. It was unclear late Monday if he was cited for speeding.
